Overbrook, known also as O.B., is in the east end of Ottawa, on the east side of the Rideau River, across from Lower Town and Sandy Hill, and just to the south of Vanier and Rockcliffe. The neighbourhood's defining streets are east-west Donald St and Queen Mary St, which run from the river to St Laurent Blvd. This community is increasingly popular with new families and empty nesters that look to live on the edge of the downtown core, while also enjoying open, green space. Along the south edge are the Queensway/417 and the industrial buildings along Coventry Rd.
